ADJUSTA'BLE OARLOCK SLEEVE Filed March 18, 1936 Patented Apr. 13, 1937' ADJUSTABLE OARLOCK SLEEVE Frank William Fraser, Vancouver, British Columbia, Canada Application March 18, 1936, Serial No. 69,548 In Canada February 3, 1936 1 Claim. (01. 9-24) This invention relates to an improved adjustorifice in the lug l5. The ring l4 extends subable oarlock sleeve.

An object of the present invention is the provision of an oarlock sleeve that may be fitted to oars stantially the full width of the flange l2.

Said flange I2 is recessed at l8 on one side of the split l3 and at IS on the other side of said 5 of any of the standard sizes. split, the latter recess opening out on the periph- 5 Another object is the provision of an oarlock ery of the flange at 26' in order to allow the sleeve that may be firmly mounted on the oar bolt I! to be inserted in the lugs l5 and I6. without the necessity of using long nails or the If desired, the ring it may be provided with a like which weaken the oar. vertical flange 2i which terminates adjacent to A further object is the provision of a device the lugs l5 and it. This flange is desirable 10 of this character of strong and simple construcwhen the oarlock sleeve B is formed of leather tion and which may be very easily manufactured. but may be used with other materials as well.

Heretofore it has been necessary to provide a The flange 2| re-inforces the portion of the different sized oarlock sleeve for each type of car flange l2 lying outside the ring it. Since the manufactured. Another disadvantage of the lugs l5 and IE re-inforce the flange l2 around 15 known oarlock sleeves is that they are formed the recesses l8 and l9, it is not necessary to have with an enlarged flange made up of a series of the flange 2i extend all the way around the ring layers of leather secured to each other and to M. the oar by means of a plurality of long nails or A plurality of short screws or nails 22 are used the like which extend into the oar in substanto fasten the sleeve it to the oar shaft A. These 20 tially the same plane, thus weakening the oar at screws or nails are spaced from the split l l. the point where there is the greatest strain. These oarlock sleeves are all manufactured, as

What I claim as my invention is: An adjustable oarlock sleeve comprising a tubular member, an enlarged flange formed with the member, said member having a split aligned with a radial split in the flange, an open ring embedded in said flange the free ends of which are spaced from the split in the flange, orificed lugs formed on the ends of said ring extending outwardly to the periphery of the flange to act as guides, a, vertical flange extending around the ring and terminating adjacent to said lugs, said enlarged flange and tubular member being adapted to be cut away between the lugs to fit 10 oars of various sizes.
